Most guides start by explaining how to do this one time only patch so later one, we can select "quick access" patch.

My questions:

1) You are saying that this only needs to be done once but, what if I update my firmware (MAIN/FS/CUSTPACK), will I need to re-apply this quick access patch?

2) What is this quick access patch good for? Does it speed up the phone, or the patching?
